    Question

    If 1 is subtracted from each odd digit and 2 is added to each even digit in the number 6249729, what will be the sum of the digits that are second from the left and second from the right in the new number thus formed?

    A.

    6

    B.

    12

    C.

    10

    D.

    8

    Correct option is D

    ​Given number:
    6249729
    Now, 1 is subtracted from each odd digit and 2 is added to each even digit in the number, we get-
    New number = (left end) 8468648 (right end)
    Sum of the digits that are second from the left and second from the right in the new number thus formed = 4+4 = 8
    Thus, correct option is (d).
